Thibaut Astic and Douglas W. Oldenburg
These notebooks were used to generate the figures shown in the article A framework for petrophysically and geologically guided geophysical inversion. We perform PGI over various examples: a 1D MT layered-earth, a DC profile over 2 cylinders, a stitched FDEM survey for saline water intrusion
There are 3 notebooks in this repository:
To setup your software environment, we recommend you use the provided conda environment
conda env create -f environment.yml
conda activate pgi-environment
alternatively, you can install dependencies through pypi
pip install -r requirements.txt
Please make an issue if you encounter any problems while trying to run the notebooks.
